--------------------------------------

Sorry, that should be 

if(defaultNames!=null && defaultNames.length>0)

> When no invoker proxy bindings are configured, org.jboss.metadata.BeanMetaData.getInvokerBindings() returns a NullPointerException.  This is caused by the fix for JBAS-4444.  org.jboss.metadata.ConfigurationMetaData.getInvokers() used to return a zero-length array when no bindings were configured but it now returns a null value which BeanMetaData.getInvokerBindings() does not properly handle:
>    public Iterator getInvokerBindings()
>    {
>       if (invokerBindings == null)
>       {
>          // See if there is a container default invoker name
>          String[] defaultNames = configuration.getInvokers();
>          if (defaultNames.length > 0)                               // Line 263 NPE
>          {
>             invokerBindings = new HashMap();
>             for (int count = 0; count < defaultNames.length; count++)
>             {
>                invokerBindings.put(defaultNames[count], getJndiName());
>             }
>          }
>          else
>          {
>             // Use the hard-coded defaults
>             defaultInvokerBindings();
>          }
>       }
>       return invokerBindings.keySet().iterator();
>    }
> Changing line 263 to if(defaultNames!=null && defaultNames.length()>0) would eliminate the NPE.
